I came across an Ultra varmint in 22Mag at a decent price and the thought hit me why not a Quad Ultra with the 17m2, 17hmr,22lr, and the base 22mag. Even if you topped it off with Burris's Quad 3x9 rimfire scope ($300) and the cost of the additional barrels and fitting, say($200-$250 give or take) it could all be had at roughly a third of the cost of the Sako ($1700-rifle,$300-Burris scope,+ taxes). Any one else thought along these lines? Would the barrels listed as fitted to Sportster frames only work? and of course the unlisted 17m2?
